Yep! Familiar with both. I flew AH-1F Cobras with the 20 and AH-64A and Ds
had the 30mm chain gun. 20 is a bit more accurate due to smaller round and the spin of the 3 barrel gatling gun. 30 is more area fire weapon due to burst radius of the 30mm and the pattern is more scattered. Still highly accurate with fire control computer continuous solutions, laser range finder designator giving continuous range...Man those were the days!!
